Throughout recent election campaigns, from the articles, speeches, broadcasts and lectures of North America’s chattering class, the public has been hearing a lot of condescending reference to something the liberal left likes to call “trickle down” economics.
Progressive humourists, entertainers, politicians and academics generally use the term to disparage the merits of free-market capitalism. More specifically, they are referring to “supply side economics” which shaped the policies of the Thatcher and Reagan revolutions of the early 1980’s. It is something they say we should never return to.
